It was in the evening of the next day that Lydia received a wire from Jack Glover. It was addressed from London and announced his arrival.

"Doesn't it make you feel nice, Lydia," said Jean, when she saw the telegram, "to have a man in London looking after your interests--a sort of guardian angel--and another guardian angel prowling round your demesne at Cap Martin?"

"You mean Jaggs? Have you seen him?"

"No, I have not seen him," said the girl softly. "I should rather like to see him. Do you know where he is staying at Monte Carlo?"

Lydia shook her head.

"I hope I shall see him before I go," said Jean. "He must be a very interesting old gentleman."

It was Mr. Briggerland who first caught a glimpse of Lydia's watchman. Mr. Briggerland had spent the greater part of the day sleeping. He was unusually wakeful at one o'clock in the morning, and sat on the veranda in a fur-lined overcoat, his gun lay across his knees. He had seen many mysterious shapes flitting across the lawn, only to discover on investigation that they were no more than the shadows which the moving tree-tops cast.

At two o'clock he saw a shape emerge from the tree belt and move stealthily in the shadow of the bushes toward the house. He did not fire because there was a chance that it might have been one of the detectives who had promised to keep an eye upon the Villa Casa in view of the murderous threats which Jean had received.
